Does anyone out there have any info on intial setting for rider sag on rear suspension. I already am aware that I need the heavier rate shock spring. Does Yamaha also call out a free sag dimension (no rider on sled).
Also been hearing rumors about a set tape from Yamaha, explaining set on the new RA? Is this true?

I asked the same question awhile back. I believe you measure the spring lenght with track off the ground, then sit on sled with gear and the spring should be 40-45mm shorter. I weigh about 220 and
installed the heavier spring and have it on setting 1 out of 7 and seems to be good according to the measurement. This is on an Attak also, but haven't had a chance to ride it yet.
